not sure mikey, but these appear to be some type of 'hover fly', these are honey bee and wasp look a likes. drone fly, flower fly, many common names.
look up
'drone fly, Eristalis tenax' and also '
flower fly wasp (Helophilus pendulus )', or '
Syrphid Flies'...... these are of the '
syrphid or Syrphidae (Taxonomic Classification). (for north caroliina) images and articles.
the drone fly can look like a honey bee and perhaps an old honey bee, as perry mentioned. what caught my eye was the first picture, the distinct coloring, hairless, and wing structure.
i found this real quick from north carolina state university department of entomology on the hover fly:
